TADO lockout of boiler

Ive noticed something - if I want to boost the temp in my flat from say 18 deg to 21, sometimes the boiler will NOT flame (return flow temp stays at 25 deg without the boiler firing up) even with the smart TRV fully open, unless I turn all rooms off first on the app then hit boost. Has anyone else had this issue? Is it due to the spiel that's in the TADO manifest where it says it tries to limit how often the boiler is asked to heat?

    Something isn’t working properly there. I think you’re using ems bus? Might be a communications issue between tado and the boiler.
  • I think so too....often it's a few minutes for anything to happen as well

    You might just be trying to fight the machine.

    Turn it up, get on with life for a while, then check it.
